Nomenclature Database

Vicent Miquel Rodrigo Peñarrocha


Abstract - Many people who need to write technical documents do not know that there exist standards for writing letter symbols. When a Lecturer or Professor gives a lesson, the symbols used are transmitted to the students so they learn which symbols must be used for each magnitude. But in many cases, the symbols employed by the professor are not the standard ones for that magnitude. And in different subjects, different symbols are employed for the same magnitude, so students are confused. This database contains more than 400 letter symbols, units and international standards related to nomenclature. It is used to correct nomenclature in the Departamento de Comunicaciones of the Universidad Politécnica de Valencia. The database is compressed in a self-extracting archive. It works on a PC with the Microsoft Access 2.0 program.



Using the Database

The database is compressed in a self-extracting archive. It works on a PC with Microsoft Access 2.0. To use this database, save the file NOMENCLA.EXE in a directory and run it. It will create two files. The one with extension MDB is the database. Open this file with Microsoft Access. The next picture shows what can be seen when opening the database.

Under the name "Data:" five buttons appear:

Under the name "Listings:" two columns of buttons appear. From the ones on the right, different subjects can be selected and the corresponding listing appears.

The ones on the left contain symbol listings in different orders:

As an example, one part of a global listing by name is included in the following figure.
